MASTER BATTERY DISCONNECT SWITCHES

Metal Bodied

Master battery disconnect switches are installed in electrical systems allowing the operator or technician to completely disconnect the electrical current running through your commercial vehicle or piece of equipment. Being able to isolate the flow of electricity has many safety, security, and cost-saving benefits. SPST switches disconnect the battery circuit only, while DPST options will disconnect the battery and the alternator or generator field circuit as well Plated steel case with a die-cast lever and copper contacts
